United Airlines and Boeing Co. experienced a bumpy 24-hour beginning late Tuesday with an emergency landing of a new 787 Dreamliner, followed by an unrelated Federal Aviation Administration order requiring inspections on some of the jets because of fuel line problems.

The Dreamliner created quite a local buzz as the airliner opening the Asian market to Denver. It is to be used on a Denver-to-Tokyo nonstop flight, scheduled to debut in March.

Reports of fuel leaks were traced to improper assembly of the engine’s fuel-feed couplings on 787 airplanes at the Boeing manufacturing facilities. The FAA order applies to 787s that already are in service and those still in production.

The FAA’s airworthiness directive goes on to say that — if these installation procedures are not fixed — it could lead to engine power loss, shutdown or fires caused by fuel that leaks onto hot engine parts.

In a separate incident, United flight 1146, carrying 174 passengers and 10 crew members from Houston to Newark, made an emergency landing in New Orleans on Tuesday, when one of its six electric generators failed. The aircraft was the third 787 that United received from Boeing on Nov. 27.

The pilots received a flight deck notification, warning them that the generator had failed, but the aircraft never lost electrical power. “The many redundancies built into the aircraft allowed it to be powered by the remaining five electric power sources,” United said in a statement.

The aircraft will remain parked at New Orleans while United replaces the generator and runs additional inspections before returning it to service.
